1.5 Power Supply and Battery
This analyzer drives by a battery and bus power from a USB port.
ڦReplace the Battery
If the analyzer cannot drive by the battery any longer, or the running time after charging is extremely short,
replace the battery. Remove the battery cover and replace the battery.
Battery is a consumable part and LINEEYE does not warrant it.
Battery is necessary for saving data in the storage device during the power shortage. Insert the battery all the time.
ڦLithium primary battery
Measured data in the SRAM, setting data, clock IC are saved by the Lithium primary battery for about 5
years even though analyzer turns o the power.
If “Initialized” is displayed at the opening screen every time, it is necessary to exchange the Lithium primary battery.
Please contact LINEEYE or LINEEYE distributor.
Use the USB charger with specication below.
Output voltage ：4.9V~5.5V
Output power ：10W or more （recommend 2A or more）
To replace the battery, purchase LINEEYE Lithium ion battery (model: P-
26LS1), and do not use any other.
ڦCharge the Battery
Lithium ion battery is charged while analyzer runs by the USB bus power.
Factory setting is “Normal charge” and charging time is following.
While analyzer is turned o ：Take about 6 hours for full charge.
While analyzer is turned on ：Auxiliary charging. Take much time for full charge.
Change the charging type from system menu to save battery life or to charge faster.
2.7 System Menu (Auto Power O and Charging Battery
Before using the product for the rst time, charge the battery rst.
Charge the battery under the condition of 5 ~40 °C. If the temperature is below 5°C, it cannot charge the battery.
It cannot charge the battery full if the USB charger or USB bus power is below 4.8V.
Charge the battery full before putting it aside for a long time. In this case, charge the battery once in a half year.

ڦMode
Select DTE or DCE mode for Simulation/BERT function.
It is used for changing the input/output status for selected port
during the measurement.
If it is a Monitor function, or not running (stopping) Simula-
tion/BERT function, all signals of measurement port become
input status.
 In general, PC and data terminal equipment are “DTE”, and modems and terminal adapters are “DCE”.
When using the simulation function or BERT function, the selected DTE/DCE is displayed at the top of the screen.
However, when TTL port is selected, as there is no distinction of DTE/DCE, thus "Sim" is displayed. When using the
monitor function, "Mon" is displayed regardless of this setting.

□ BERT (Bit Error Rate Test)
The analyzer sends the test pattern and compares the received
data with the test pattern. This is useful to evaluate quality of
data communication line.

When the simulation function or BERT function is selected,
"DTE" or "DCE" or "Sim" is displayed at the top of the screen
depending on the interface mode setting.
2.4 Measurement Function
Press [Menu], then touch“Function”.
Select the operation mode and function. Touch “ Advanced settings” for addition settings. For Simulation function,
touch
“ Tx-data registration” to register transmission data.
□ Monitor
The analyzer monitors transmission/reception data at real time,
and analyzes data and errors.
Select “ONLINE” for general use.

Protocol
Touch“Protocol” and select the protocol of target devices. ASYNC is the widely used communication.
ڦProtocol
Selection Protocol Description
ASYNC Asynchronous Communication which uses the start and stop bit.
Ex.) PC COM port, UART communication.
SYNC･BSC Character-SYNC Communication which uses 1 or 2 bytes of SYNC characters.
Ex.) BSC, JCA procedure etc.
HDLC･SDLC Flag-SYNC Communication which uses the ag bit patterns (7Eh).
Ex.) HDLC, SDLC, X.25, LAPD
ASYNC-PPP PPP (ASYNC typed) Asynchronous which uses ag characters (7Eh).
Ex.) ASYNC-PPP communication used for WAN etc.
MODBUS MODBUS(ASCII/RTU) Communication which is wildly used for FA devices.
[LE-3500XR only]
I2C I2C Communication which uses 2 lines (SDA and SCL) at TTL level.
SPI SPI Communication which uses 3 (or 4) lines at TTL level.
Burst Clock-Sync Communication which has the Sync-clock only when transmit-
ting/receiving data.

Communication Speed
Set the communication speed of target devices. For simulation function, it is able to check the tolerance of target
device by setting the dierent speed on purpose.
Touch and pre-set speeds (widely used) are displayed. Swipe the screen to display more.
Arbitrary Speed
Set any arbitrary speed by [0] - [9] and alphabet keys. [D] rep-
resents “kilo”, [E] represents “mega” and [C] is for inserting
“comma”.“M”,“k”, and “ . ” are also appeared on the right bottom
of screen.
Exp.: To set“945.6kbps”, input [9] [4] [5] [C] [6] [D].
ڦTXD speed
Set the communication speed of transmission line. After set-
ting this, RXD speed is automatically set.
